1215 Dual 15-Band Graphic Equalizer

The dbx 12 Series were designed to meet the needs of the most
demanding sound reinforcement environments, while offering the
simplicity of straightforward controls. The 1215 provides standard
features like dual channels, 15 2/3 octave bands, ISO frequency
centers, +/-12 dB input gain range, and switchable 40Hz/18 dB per
octave low-cut filters, but also includes other thoughtful features.
These include 45 mm faders; selectable +/-6dB or +/-15dB boost/cut
range for precise gain adjustments; XLR, barrier strip, and 1/4'' TRS
connectors for installation ease; balanced inputs and outputs for quiet
operation; and chassis/signal ground lift capabilities for quick hum isolation.
The visionary design of the dbx 12 Series makes your job easier.

The dbx 12 Series Equalizers were precision engineered to provide years
of maintenance-free operation in any application. The magnetically isolated
transformer, electronically balanced/unbalanced inputs and servo balanced/
unbalanced outputs, RF-filtered inputs and outputs, and power-off hard-wire
relay bypass with 2 second power up delay were steps our engineers took
to ensure compatibility for all installations. Only the best components were
utilized, yielding a 10Hz to 50kHz frequency response, greater than 90dB SNR
(ref +4dBu), less than 0.005% THD +Noise (1kHz at +4dBu), and interchannel
crosstalk of less than -80dB from 20Hz to 20kHz. All this attention to detail
is contained in a 2U steel/aluminum chassis.
